This produces... ...heat which boils water and creates steam 1 of 11 What do nuclear power stations use? Uranium 2 of 11 What is the nuclear reaction called? Fission 3 of 11 Both power stations use what to turn the turbines? The steam 4 of 11 What is a chain reaction? When a uranium nucleus absorbs an extra neutron it splits, releasing energy and more neutrons 5 of 11 What is nuclear fusion? The process by which heat energy is realeased when nuclei join (fuse) together. 6 of 11 What do scientists place in the reactor to stop the nuclear reactions getting out of control? Control Rods, this absorbs some of the neutrons 7 of 11 When two nuclei fuse together a large amount of what is released? Heat energy, this can only happen at extremly high temps 8 of 11 In 1989 what did Martin Fleischmann and Stanley Pons claim? That they had acheived cold fusion 9 of 11 What are the 3 types of nuclear radiation? Alpha, beta and gamma 10 of 11 What type of radiation is used to treat cancer? Gamma 11 of 11
